On June 29, 2021 at 00:31 UTC, a magnitude 4.7 shallow crustal earthquake struck 10 km NNW of Palma Sola, Argentina, at a depth of 10.0 km and coordinates -23.8943°, -64.3535°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
